This book was insightful, but much of it wasn’t helpful to me.
Because many people going through a breakup or divorce have children involved (and that’s when such issues get messiest), that’s what a lot of the book focused on and gave examples of. For me, as a person without children now or in the future, that gave me sections to speed-read or skim through.
Still, the book was full of good information about ending relationships with people with “cluster B” traits that show patterns of behavior common to narcissist, borderline, and antisocial personalities. My language in this review will be sorta vague for the same reasons the authors chose to do so: even professionals disagree about the diagnoses of these personality disorders, so it’s not anyone else’s place to even attempt to diagnose another. And, what’s more, don’t ever explain to a judge or a partner that you think the partner has a personality disorder. Don’t diagnose. Don’t spread your false diagnosis. Keep it to yourself. Just focus on the patterns of behavior.
One large point made in the book is that such people often “split” on former partners, as these people tend to see others as all good or all bad. At the same time, the authors make it a point to explain that these are unconscious defense mechanisms. For example, people with BP traits often do such things when attachment is threatened, people with NP traits do so when their self-image is questioned, and people with either/both do it when they lose control.
A major aspect of the book I appreciated is that the authors repeatedly made the fair statements that people with these traits aren’t bad people, that these people just want to be happy too, like everyone else. These people just ended up with the traumas and personalities that they ended up with, and most of the time don’t understand the self-sabotage they’re doing. These people need help (like most of us do). However, again this is a good repeated point of the authors’, that’s not the responsibility of any partner.
People with personality disorders, or traits similar to them, can appear normal or as great people to others. Yet, in time, the traits come out. These people struggle with taking responsibility for their actions because they feel they’ve acted properly, blaming others for “making them” behave in certain ways.
I found BPD and NPD stuff most interesting. BP traited people tend to “feel unworthy and empty, lack a sense of self, and constantly fear real or imagined abandonment.” Their brains, in scans, show the amygdala (emotional intensity center and how we can return to normal) more active than those without BPD. They’ve frequently had issues in childhood with abuse, (perceived) ineffective parenting, mismatch of parents/children, home lives that intensify negative views of the child, and abandonments (including perceived ones).
A common way the authors chose to explain people with personality disorders is as if they are drunk. It’s a good analogy in many ways, as “their thinking is continually ‘under the influence’ of their cognitive distortions.” They only give info, never taking any in. And, like some people in various stages of drunkenness, don’t realize they’re being influenced (or how much).
Those distortions were a big point of learning for me in the book. Distortions are defense mechanisms set off by alarms - which are often false, thanks to the overactive nature of the person’s amygdala. They truly feel in danger, powerless, and out of control. “Their extreme feelings create their own problems.” They see events through their distortions, so have different perceptions of the past and present than most would, given the same inputs. The main distortions are “exaggerated fears, all-or-nothing thinking, jumping to conclusions, emotional reasoning, and projecting.” BP traits would be like alternating between clinging behavior and rage. During breakups, they may mess with money. In attempt to feel better and more in control, they try to control others (consciously or not). They frequently use emotional reasoning: feel strongly about something and hold onto “facts” that fit that feeling - as shown when they get hung up on a minor detail in a discussion because of an emotion triggered by it. Because of much of the above, they don’t do well with negotiations and compromise. The distortions show up in “If you cared about me...”, “If you respected me...”, and more clearly verbally abusive statements.
The book explains that the best approach is an assertive one: “balancing patience and flexibility with clear communication and deadlines.” With patience meaning “allowing time for the other person to adjust” and flexibility meaning “room to negotiate the details.” It also explains that people with personality disorders can actually be very good in court, grabbing attention with their extreme emotions (and their distortions). It also explains that, to combat this, the key is assertively supplying ample evidence to disprove their story and to align everyone’s views closer to a reality.
There’s a ton more in there about fighting for child support and custody, the processes best suited for different situations, and so on. The end of the book focuses on how to move on with life afterwards, again urging balance. “Avoid being too close or too rejecting. Avoid the common error of cutting the person off or trying to be really close friends. Both approaches can easily backfire.”
